To all whom it 'may concern:

Be it known that I, THOMSON HOWELL,

The present invention relates, generally,

to improvements in carbureters for gas engines; and the present invention has for its principal objects to provide a novel and simply constructed apparatus or device in which a perfect mixture of gasolene with air is caused to produce the explosive gas which is to be exploded in the cylinder of the gas engine.

The invention has for its further object to provide in connection with the gasolene intake, a novel means for regulating the amount of gasolcne permitted to enter thc carbureting chamber, to be mixed therein with the air to form the explosive gas, this said regulating means being automatic in its action and being controlled by the needs of the engine. i I I Other objects of this invention not at this time more particularly set forth will be clearly evident from the following detailed description of the same. .i

lVith'the various objects of t present invention in View, the same consists, primarily, in the novel carloureter for gas-engines hereinafter more fully set forth; and, furthermore, this invent-ion consists in the general arrangements and combinations of the varions devices and parts, as well as in the de# tails of the construction of the same, all of which will be presently more fully described, and then iinally embodied in the clauses of the claims which are appended to and which form an essential part of this specification.

The invention is clearlyillustrated'in the accompanying drawings, in which Figure 1 is a longitudinal vertical section of the novel carbureter. Fig. 2 is a vertical cross-section taken on line2--2 in said `F ig. 1, and looking in the direction of the tical section, similar to Fig. 1, illustrating more particularly the gasolene-intake4 and vregulating means connected therewith, when the same is in ope-ration and is admitting the gasolene into the carbureting chamber.

Similar characters of reference are elnployed in all of the above described views, to indicate corresponding parts.

Referring now to the several figures of the drawings, the reference-character 1 indicates a complete carbureter, illustrating one form of the present invention, the sa-meconsisting, essentially, of a main shell or body 2, provided with a closed bottom 3, and is made with ari open top, having a screw-thread 4 in operative relation with the gas-engine apparatus. The said main shell or body 2 is further provided with a forwardly extending member or portion 5, the same being formed with a hole or opening 6, the said forwardly extending member or portion 5 being further provided with `an annular flange 7 Y A tubular member or shell 8, provided at one end with an annular flange 9, is connected with said main shell or body 2,-by placing the said annular ila-nge 9 in alinevment with the annular flange 7 of the forwardly extending member or portion 5 of said main shell or body 2, and securing the same together bymeans of screws or bolts 10, or any other suitable fastening means, which are passed through holes in the said anges 7 and 9, substantially as shown. This said tubular member or shell 8 providesI a carbureting chamber l1 into which the air lis drawn or sucked, through the open free end thereof, preparatory `to mixing the gasolene therewith. The said tubular member or shell 8 is furthermore provided in its interior with suitably disposed arms formed with a centrally disposed hub 12, said hub 12 andv the arms 13 being preferably formed integrally with the said tubular memberor shell 8. The hub 12 is provided with al centrally disposed hole Vor opening supplied with the interior screw-threads 14. Secured in this hub 12 by means of its screw-threaded end 15 is a gasolene intake-pipe and valvemechanism 16, which comprises a tubular opening or duct 1T extending longitudinally into the said intake-pipe 1 6, said opening or duet 17l terminating in a cone-shaped valveseat 18. Extending from this seat 18isanother on its outer surface for attaching the same tubular opening or duct 19 of smaller diameter in cross-section than that of the opening or duct 17, this said' opening or duct 19 extending longitudinally through and to the free end of the said-intake-pipe 16. The free end of this saidintake-pipe 16 is provided with a screw-thread 20, by means ofl Concentric with the said intake-pipe 16 is a tubular member 22 whic is provided at one end and upon its opposite sides with longitudinally disposed slots 23, said slots being arranged over and registering with the outer ends of the said holes or perforations 21 of the intake-pipe 16. This said tubular member 22, when properly adjusted in its operative relation as above described, may be secured in place bymeans of the Set-screw 24 which is provided with the operating finger or thumb-piece 25 or,'the said parts or members may be otherwise secured, if desired. The said tubular member or shell 8 is further provided in its interior with another centrally disposed hub 26 which is formed with a hole or opening 27, this hub being supported by suitable arms 28 which are preferably formed integral with the said tubular member or shell 8. y

Slidably arranged in the hole or opening 27 of the hub 26 is the valve-stem 29, of what is ordinarily termed a needle-valve, said stem extendin into and being slidably arranged in the tu ular` opening or duct 17 of the intake-pipe 16. The said valve-stem is provided upon its free end with a coneshaped portion 30 adapted-tonormally be seated u on the valve-seat 18, so as to close the tubu ar opening or duct 19. The'valvestem 29 is furthermore adapted to close the Y said plurality of laterally-extending holes or perforations 21 against .the 4passage of the gasolene therethrough. Y

A disk 31, preferably'provided with a hub or boss 32is suitably securedupon the? end of the valve-stem 29, preferably, by means ofa pin 33. I

The said main shell or body 2 is provided with a boss or enlargement 34 having a 'hole-therein which is providedwith a screwthread 35, and the reference-character 36 lindicates an adjusting screw-which penetrates into the interior of the said main shell or body 2. Securedupon the inner end of said adjzusting screw 36is a flanged nut or collar 3 the same being preferably secured b means f the pin 38, but any other suitable means of fastening may be employed. Arranged u n this collar or nut 37, so as to engage with the `flange thereof, -isone end ofa spring, as 39, the other end of said` spring engaging with the hub 32 of the disk 31. The purpose of themspring 39 is to normally keep the cone-shaped end 30 of the valve-stem 29 seated upon the seat 18 of the gasolene intake-pipe 16; and, at the same time causing said stem to maintain a closed relation of said laterally extending .holes or perforations 2, as 'will be clearly evident. The outer end-portion of the adjusting screw 36 is provided with an operating linger or thumb-'piece 40, by means of which in turning the adjusting screw 36, the said screw can be made to increase or decrease the tension of the spring 39, as will be clearly understood from an inspection of Fig. 1 ofA the drawings. Vhen a proper adjustment of the tension of the spring 39 has been secured, there is provided in connection with the adjusting screw 36.'a lock-nut 41 which is screwed upon the shank of the adjusting screw and against the outer face of the boss 34 to lock .the adjusting screw in its adjusted position. Arranged in the upper portion of the said main shell or body 2 is a shaft or spindle 42, said spindle being suitably jour- 'naled in the walls of said main shell or body 2. Said shaft or spindle is also provided at.

one end with an upwardly extending lever or actuatingvarm 43, andv rigidly secured upon the shaft or spindle, within the main .shell or body 2, is a disk 44, the same forming a regulating-valve or throttle for controlling the' amount of gas to be drawn from the carbureting chamber.

Having thus described the construction and essential parts of the novel carbureter embodying the principles of this invention, it now remains to describe the same as it operates to mix the gasolene and air to form the gas tobe supplied to the gas engine, and the novel means of regulating Isuch admixture.

In the ordinary gas-engines the mixture of gasolene and air is drawn intoV the cylinder of the engine by the suction of the moving piston.

In the present invention, when the moving piston in the engine-cylinder begins this sucking'action, the suction which is createdin' the interior ofthe main shell orbody 2 causes the disk 31 to be drawn inwardly against the tension of the spring 39. .This action causes the cone-shaped end 30 ofthe valve stem 29 to be withdrawn from the seat 18, and allows the tubular opening or duct 19 to be opened, and thereby permits the gasolene to flow into the tubular opening or duct 17. The valve" stein 29, as it is drawn outwardly, also exposes one or more of the laterally extending holes or perforations 21 and permits the gasolene to pass therethrough and through the narrow slots 23,

from whence ift is sprayed into the carburetlngchamber 11, .1nwhlch the gasolene is y mixed withI the air which is sucked into the i interior of the main shell Vor body 2 and thence into the engine cylinder.

The. disk 44 which forms a throttle .or regulating valve may be turned' or adjusted so as to increase or decrease the power of the suction, as will be evident. VThe stronger the suction, the farther out the disk 31 and the valve-stem 29 will be drawn, and consequently a greater number of the holes or perforations 21 are exposed to the passage of the gasolene, which results, as will be clearlyl evident, in an` increased percentage of gasolene being mixedl with the air and a heavier or more highly charged explosive mixture will be the result.

It will thus be clearly understood, that the present invention rovides'an extremely simple, but a very e ectively operating carbureting Idevice in which the strength `of the gaseous mixture is automatically regulated `according to the needs of the engine.

The device has practically few part-s, and

these of very simple construction and operation, hence the carbureter is not likely to get out of order or cause any undue trouble or annoyance. y v

I am aware that changes may be made in the various arrangements and combinations of parts, as well as in the details of the construction of the same without departing from the scope of the present invention, as defined in the appended claims. Hence, 1 do not limit my invention tothe exact arrangements and combinations of the devices and parts, as illustrated in the accompanying drawings, and as described in the accompanying specification, nor do I confine myself to the exact details of the construction of the said parts.
